>The finite field GF(pn) has characteristic p.
>2X=0 or -X=+X,
>
>i.e. there is no substrctions (because substraction becomes addition) and you can't devide by 2 (=zero).
>
>Put differentilty, X\mapsto -X becomes identity.
>
>And then e.g. X\mapsto X^2 now has only one fixed point, because both X and (-1)*X are actually the same
